I bought my first Dodge truck last year and have enjoyed the truck very much. It's a 1998 with 180,000 miles.

Last summer It developed a problem with the AC. It blows good cold air but sometimes I can hear something in the dash closing and the entire air flow stops. The fan keeps blowing but nothing comes out. It does this on the vent setting as well. Is there something that closes off the entire air flow from the plenum? Is it servicable. Anyone ever heard of this problem?

I appreciate any help or advice. I'd hate to have to dump a ton of cash into it at a dealer but I sure could use some AC when those steamy summer days finally return.
